I've been HODLing copper for a few years, and I've even posted about it on Bitcoin Talk.I also save lead. It isn't as valuable, but the weight/volume ratio is good.
Lead?
The prices here are 50$ for 99% lingots of 25kg. If we talk about scrap prices it's around 1.2$ per kg.
Of course, it's heavy as hell and does save a lot of space but....I would stick to something that doesn't require a pick-up truck to transport something worth the equivalent of one week wage.
In India this is big business and a lot of people are salvaging precious metals from electrical devices, but it is dangerous, because the burning of this, gives off poisonous gasses that are very harmful to those people.
I had one case when we were called because of some gypsies burned rubbish that had PCB (biphenyl) in it, god knows from where did they get that much trash the first medics that arrived at the scenes couldn't do much because they weren't equipped with any kind of protection for such fumes.
And we were in the EU at that time, I imagine in India is pretty worse from what I see in documentaries.
Now back to the op
At first, my friend (Daniel) taught is boring for us to spend so much amount of time gathering reasonable amount of such electrical device, $ separating the copper wire from the adpater or removing the copper from it's motor in case of electrical fan until i stumble across the possible of make more cash in form of bitcoin just by gathering most of these stuff
I really don't get your business plan.
How can you make more cash by gathering this and be paid in Bitcoin rather than fiat?
Do you want to trade waste copper for bitcoin?
It really doesn't matter what choice of payment you will use, buyers will look for the cheapest price, seller for the highest, and international stuff...the cost of transport will be killing you.
If I'm missing something in your plan, please elaborate!!
